In the predictable rush to cover natural disasters, political upheaval and the fall of empires, many reviews of 2011 will no doubt fail to note our blogging exploits – so we've been forced to write our own.

Creative Review allowed me to take control of their Twitter account and I used the opportunity to launch the first ever #CreativeAmnesty – a chance for creative professionals to share their worst work in an atmosphere of mutual sympathy and tolerance.

It was good fun, with entertaining and admirably honest contributions coming in from various corners of the globe. I believe I also managed to destroy the careers of various competitors along the way.

I’ve put together a rough timeline of how the day developed, using Storify.

Today should be an interesting day. Creative Review have invited me to guest edit their Twitter account.

It's not often you get the chance to tweet to 372,000 people, so I thought I should use it to get an interesting conversation going.

It struck me that most creatives are comfortable talking about their best work, but conversation about the worst stuff is understandably taboo. It's a shame because everyone has a story about a nightmare project and they're usually amusing, not to mention instructive.

For one day only, share your most shameful creative projects with impunity. No sniping, no shame. Just sympathy and mutual support.

I'm inviting people to post their contributions on Twitter using the #creativeamnesty hashtag. Pithy project descriptions are fine. Extra points for images and links. You can also blog about it in more detail elsewhere and tweet a link.

—Me talking about some horoscopes I once wrote—Sue Asbury recalling some ethnically sensitive balloons—Stuart Watson of Venture Three discussing some awkward student plagiarism—Richard Weston (Mr Acejet170) confessing to a series of career low-points—And a charming tale involving a John Travolta cut-out from awards magnet Chris Doyle

The site will be updated as the day goes on, with contributions from the great and good of the creative world. Please join in.
